Effect of Raman Opalescence on Titanium Dioxide Micropowders Under Pulse-Periodic Laser Excitation

Abstract

A method is proposed for recording the amplification of Raman spectral signals using photon traps and light guides. The Raman spectra of titanium dioxide micropowders placed in a photon trap were studied using pulse-periodic laser excitation generated by a copper vapor laser. A combination opalescence mode can be realized using existing photon traps and fiber-optic techniques in titanium dioxide microstructures at room temperature. This mode consists in an abnormal increase of the Raman scattering intensity into the secondary radiation spectra.
